NAME

       mlib_ImageColorRGB2CIEMono_Fp - RGB to monochrome conversion

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageColorRGB2CIEMono_Fp(mlib_image *dst,
	   const mlib_image *src);

DESCRIPTION

       The mlib_ImageColorRGB2CIEMono_Fp() function performs a conversion from a red/green/blue to a monochromatic image. The source image must be
       a three-channel image. The destination image must be a single-channel image.

       It uses the following equation:

	 dst[x][y][0] = 0.2125*src[x][y][0] +
			0.7154*src[x][y][1] +
			0.0721*src[x][y][2]

PARAMETERS

       The function takes the following arguments:

       dst    Pointer to destination image.

       src    Pointer to source image.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
